Properties
Methods
Equals, FindName, GetHost, GetValue, SetValue
Remarks
For mouse input that is used for ink support in leiu of a stylus, DeviceType returns Mouse.
Examples
The following example uses the PressureFactor property to determine the size of a stroke. The PressureFactor is obtained from the first StylusPoint of each stroke, then the stroke Width and Height is calculated by multiplying the PressureFactor by 20.

var agCtrl;

function InkPresenterMouseMove(sender,args)

// Release the mouse
function InkPresenterMouseUp(sender,args)
{
newStroke = null;
}
// Set the size of the stroke based on the initial pressureFactor of the stroke.
function SetStylusStrokeSize(sps)
{
var p;
// Set variable p to the first StylusPoint in the Stroke
p = sps.getItem(0).pressureFactor;
daWidth = p * 20.0;
daHeight = p * 20.0;
